$p$-进数中的自相似集与自相似测度

Self-similar sets and self-similar measures in the $p$-adics

Kevin G. Hare, Tomáš Vávra

AI总结:

本文研究 $p$-进自相似集与自相似测度,揭示其与路径集分形的关系、唯一本质类、极大抽取及局部维数性质。

摘要:

本文研究了 $p$-进自相似集和 $p$-进自相似测度。我们证明了 $p$-进自相似集是 $p$-进路径集分形,但反过来未必成立。对于 $p$-进自相似集和 $p$-进自相似测度,我们证明了唯一本质类的存在性。我们证明,在温和假设下,$p$-进自相似集的抽取是极大的。对于 $p$-进自相似测度,我们证明许多涉及局部维数的结果与其实数对应情形相似,且复杂之处更少。这些结果大多利用了自相似性的附加结构,对于一般的 $p$-进路径集分形并不成立。

英文摘要:

In this paper we investigate $p$-adic self-similar sets and $p$-adic self-similar measures. We show that $p$-adic self-similar sets are $p$-adic path set fractals, and that the converse is not necessarily true. For $p$-adic self-similar sets and $p$-adic self-similar measures, we show the existence of a unique essential class. We show that, under mild assumptions, the decimation of $p$-adic self-similar sets is maximal. For $p$-adic self-similar measures, we show that many results involving local dimension are similar to those of their real counterparts, with fewer complications. Most of these results use the additional structure of self-similarity, and are not true in general for $p$-adic path set fractals.
